This invention relates to a sink or bathroom fixture adapted for mixing and delivering hot and cold-Water to a sink lavatory or the like and which includes a spray nozzle and means for controlling I and regulating the supply of hot and cold water and for diverting the flow to either the spout or the spray nozzle.

One of the objects of the invention is to provide a fixture of the character described which has as a part thereof a diverter valve which is simple in construction and dependable in operation and at the same time well adapted for production at comparatively low cost.

Another object of the invention is to provide a fixture having the above described distinguishing characteristic features and which includes a diverter valve which is carried by the spout and movably mounted therein for controlling the delivery of hot and cold water to either the spout or to the spray nozzle.

Further and more limited objects of the invention will appear as the description proceeds and by reference to the accompanying drawing in which Fig. 1 is a view partly in section and partly in elevation showing my improved fixture applied to a sink or lavatory; Fig. 2 a vertical sectional view on the line 2--2 of Fig. 1 and Fig. 3 is a somewhat enlarged detail sectional view showing the diverter valve in a different position from that disclosed in Fig. 2.

Referring now to the drawing, the reference character I designates a casing to which is connected a hot water supply pipe 2 and a cold water supply pipe 3 and from which leads a connection or valve structure 4. The supply of hot and cold water is controlled by suitable valves which are operated by valve handles 5 and 6, in a manner well known to those skilled in the art, Pivotally secured to the connection 4 is a delivery spout I, shown in detail in Fig. 2, and which preferably consists of a single casting having a downwardly extending circular portion 8 which fits within the connection 4 and is held in place by a suitable nut 9. The downwardly depending portion 8 has therein an axially extending bore III which is in communication with the interior of the connection or valve structure 4. The portion 8 is provided with a radially disposed groove which receives therein a split metal ring 8 Disposed over the split ring 8 are a plurality of washers which serve to prevent leakage about the nut and at the same time provide a pivotal mounting for the spout to permit the same to be swung to different angular positions. Threadedly secured with the connection 4 is a tube II which has therein an upper series of ports I2 and a lower series of ports I3, which are disposed in different planes and spaced apart a slight distance. The tube II extends through the casing I and is held in place at its lower end by means of a nut I4. The extreme lower end of the tube II is exteriorly threaded as shown at I5 and has se-' cured thereto afiexible tube or connection I6 the opposite end of which is connected with a spray nozzle I! which is preferably received on or supported by an overhanging portion of the sink or lavatory.

Slidably mounted in the tube II is a plunger I 8 which is formed of suitable material. The plunger I8 fits over the lower end of a stem I9 which is held in place by means of nuts 20 and 2I and washers 22 and 23. The upper end of the stem I9 extends through a boss 24 provided on the spout and has a handle 25 secured thereto. A packing 26 surrounds the stem and is held in place by a nut 21. The lower end of the stem is exteriorly threaded for a substantial distance and threadedly secured thereon is a stop 28 which is adjustable on the stemand serves to limit the movement of the stem in one direction. The plunger I8 constitutes a valve which is slidably mounted in the tube and movable to difierent positions therein. With the plunger in the position shown in Fig. 2, the interior of the tube is in communication with the interior of the casing I through the ports I3. The plunger I8 is slidably mounted in the tube and movable to difierent positions therein. In this position of the parts, a mixture of hot and cold water may be delivered to the spray nozzle I! through the flexible connection I6. With the parts in the position shown in Fig. 3, both series of ports I2 and I3 will be open and a mixture of hot and cold water will be delivered to the spout at full volume. When it is desired to divert the flow of water from the spout to the spray nozzle, the handle 25 is lifted to the position shown in Fig. 2 whereupon a lesser supply of water will be delivered to the spray nozzle. The size of the ports I2 and I3 is such that a mixture of hot and cold water will be delivered through the spray nozzle at about onehalf of the full volume, whereas the full volume may be delivered to the spout I, as both series of ports I2 and I3 are opened. Should it be desired to deliver a larger volume of water to the spray nozzle, it is merely necessary to adjust the stop 28 so that both series of ports I2 and I3 may be uncovered when the diverter valve is moved to the uppermost position.

It will now be clear that I have provided a fixture of the character described which will accomplish the objects of the invention as hereinbefore stated. The diverter valve consists of a very few parts but is well adapted for economical production and assembly and is at the same time simple and dependable in operation. It is of course understood that various changes may be made in the details of construction and design and arrangement of the parts without departing from the spirit of my invention and that the invention is limited only in accordance with the scope of the appended claims.

Having thus described my invention, whatI claim is:

1. A fixture of the character described comprising a casing, means for delivering .hot and cold Water .to said casing, a connection leading from said casing and. having a delivery spout connected therewith, a fitting secured in said connection and having communication with said spout at its upper end, a spray nozzle connected with the opposite end of said fitting, said fitting having a plurality of openings therein disposed in different vertical planes, a valve slidably mounted in said fitting and movable to divert the flow of water to said spout or to said spray nozzle, there being an extensible connection between said fitting and said spray nozzle and means for regulating and controlling the delivery of hot and cold water to said casing, said valve having a stem extending through said spout and cooperating means on said spout and stem for limiting the volume of Water delivered to said spray nozzle.

2. A'fixture of the character described comprising a casing, means for delivering hot and cold water'to said casing, a connection leading from said casing andhaving a delivery spout connected therewith, a' fitting secured in said connection and havingcommunication with said spout at its upper end, a spray nozzle connected with the opposite end of said fitting, said fitting having a plurality of openings therein disposed in different vertical planes, a valve slidably mounted in said fitting and movable to divert the fiow of water to said spout or to said spray nozzle, said diverter valve having an operating stem extending through said spout and cooperating meanson said spout and stem for limiting the movement of said diverter valve whereby to limit the volume of water delivered to said: spray nozzle.
